Global production of plastics reached 390 million tonnes in 2021 and is growing at 4% per year. As the amount of plastics produced increases, so does the amount of waste generated each year. With the development of several innovative recycling and reprocessing techniques, solutions have been found to give recycled content a new life. 

3D printing is attracting growing attention due to its versatility in producing complex and even bespoke products suitable for a range of different applications. However, the use of recycled content in 3D printing is still in its infancy. This breakfast session will look at some of the ways in which different recyclates can be processed and reworked.


The use of WEEE waste in 3D printing
Waste from electrical appliances and electronics (WEEE) is currently insufficiently valorised in new applications. One of the reasons is the presence of REACH-incompliant legacy additives, such as flame retardants. In this presentation, Isabel will show how flame retardants can be removed and how the plastic waste can be reused for aerospace applications via 3D printing techniques.

From PET to coffee oil: Upcycling of waste via deposition- and light-based 3D-printing
Within the Polymer Chemistry & Biomaterials Group at Ghent University, we design (photo-crosslinkable) polymers in line with the targeted application and the applied processing technique. The lecture will encompass examples ranging from extrusion-based 3D-printing of composite materials based on recycled PET waste towards digital light processing and two-photon polymerization of photo-crosslinkable molecules extracted from coffee oil. 
In addition to 3D-printing, a variety of application areas will also be addressed during the lecture.

Implementation of recycled polymers in the fused granular fabrication process
Due to the batch-wise production of many 3D printed parts, there is often a lack of efficiency when using recycled materials in a circular production process. Pieter-Jan Bulcke will give some insights into the challenges of implementing fused granular fabrication to achieve a circular production method with high efficiency and on the solutions that are being developed.

Retrofittable tooling for composites by additive manufacturing
Guido will give us a closer look to a breakthrough technology that aims at converting the value chain of tools for composites from linear to fully circular, with impacts on costs and environmental footprint.
This is achieved by substituting the currently adopted tools made of thermoset resin blocks with new and lighter 3D short-fiber-reinforced thermoplastic master models and moulds.
New challenges in design and materials are indeed presented, alongside the full potentiality of this technology.
